Preliminary Questions
1) Since velocity is a vector, the change in direction suggests there must be an acceleration present
2) Acceleration; F=ma
3) Centripetal Force
Analysis
1) Accelerations from the change in direction
2) Towards the center
3) Also increases
4) No, the velocity is squared, so by a factor of 4
5) The relationship between centripical acceleration and velocity is squared. The a is proportional to v^2.
Application
5) Friction
6) It will skid
7) 4 times as much
